Method and system synchronization of content rendering
DC CAFCFirst Claim
1. A method, comprising:
- a master rendering device rendering a first content stream; and
sending, from the master rendering device to a first one of a plurality of slave devices, a plurality of master rendering times indicative of statuses of the rendering the first content stream at the master rendering device at different times;
wherein the first slave device is configured to smooth a rendering time differential that exists between the master rendering device and the first slave device in order to render a second content stream at the first slave device synchronously with the rendering of the first content stream at the master rendering device, wherein smoothing the rendering time differential includes calculations using the plurality of master rendering times.

Abstract
A method and system for synchronizing the rendering of content at various rendering devices. Each rendering device has a device time and a rendering time. The synchronization system designates one of the rendering devices as a master rendering device and designates all other rendering devices as slave rendering devices. Each slave rendering device adjusts the rendering of its content to keep it in synchronization with the rendering of the content at the master rendering device. The master rendering device sends a message with its rendering time and corresponding device time to the slave rendering devices. Each slave rendering device, upon receiving the message from the master rendering device, determines whether it is synchronized with the master rendering time. If not, the slave rendering device adjusts the rendering of its content to compensate for the difference between the master rendering time and the slave rendering time.

11. A method, comprising:
-
receiving, at a slave device, a particular content stream; receiving, at the slave device from a master rendering device, a plurality of master rendering times indicative of status of rendering a different content stream at the master rendering device; the slave device determining a smoothed rendering time differential that exists between the master rendering device and the slave device, wherein the determining is based on calculations using the plurality of master rendering times and a plurality of slave rendering times corresponding to rendering the particular content stream at the slave device; and based on the smoothed rendering time differential, the slave device rendering the particular content stream synchronously with the master rendering device rendering the different content stream. - View Dependent Claims (12, 13, 14, 15, 16, 17)
